Abstract: A PROCESS FOR PRODUCING AN ORGANOMETALLIC TETRADENTATE COMPLEX OF COBALT BY REACTING AN ORGANOMETALLIC TETRADENTATE COMPLEX OF COBALT OF THE FORMULA:

-X1-CO(-R)(-X2(-))(-X3(-))-X4-

WHEREIN X1, X2, X3 AND X4, WHICH FORM THE TETRADENTATE COMPLEX, MAY BE THE SAME OR DIFFERENT AND EACH REPRESENTS A NITROGEN, OXYGEN, SULPHUR OR PHOSPHORUS ATOM; AND R IS AN ALKYL, ARYL, ALKARYL OR CYCLOALKYL RADICAL WITH CARBON MONOXIDE OR NITROGEN MONOXIDE AND WITH A MOBILE HYDROGEN COMPOUND REPRESENTED BY THE FORMULA R''H, SAID R'' BEING AN OXYALKYL, OXYARYL, OXYCYCLOALKYL AMINO, HYDROXY OR MERCAPTAN RADICAL, IN THE PRESENCE OF VISIBLE OR ULTRAVIOLET RADIATION DISCLOSED. THE RESULTING PRODUCTS ARE ALSO DISCLOSED AND CLAIMED. THEY FIND PARTICULAR UTILITY AS CATALYSTS IN VARIOUS ORGANIC REACTIONS SUCH AS OXIDATIONS, OXO-REACTIONS AND NITROSATIONS.

Abstract: TETRADENTATE COMPLEXES OF COBALT HAVING THE FORMULA:

-N-CO(-Y1)(-N(-))3-Y"

WHEREIN Y'' AND Y", WHICH MAY BE THE SAME OR DIFFERENT, EACH REPRESENT A MONOVALENT ANION, A HYDROCARBON RADICAL OR A LEWIS BASE, AND EACH N REPRESENTS A NITROGEN ATOM OF A TETRADENTATE CHELATING AGENT HAVING AT LEAST ONE BUT LESS THAN FOUR OXIMIC GROUPS AND PROCESSES FOR MAKING SAME ARE DESCRIBED. THE PRODUCTS ARE VALUABLE INTERMEDIATES IN THE SYNTHESIS OF OTHER COMPOUNDS AND ARE USEFUL CATALYSTS IN THEMSELVES.
